David's explains that he began developing role-playing techniques in the early days of cognitive therapy because many of the Beckian techniques, such as Examine the Evidence and the Socratic Technique--while sometimes very helpful, were sometimes a bit dry, and he wanted to include punchier and more powerful and dynamic techniques in his therapeutic toolkit. These role-playing techniques are just one part of what sets TEAM-CBT apart from traditional, Beckian CBT.

Today, he explains and demonstrates the Externalization of Voices, which is always combined with the Self-Defense Paradigm and the Acceptance Paradox. He is joined by Fabrice, of course, and "Sarah," one of the members of his Tuesday training group at Stanford. Sarah has volunteered to use a personal example in the podcast to help demonstrate the Externalization of Voices.
